PROCESS AND INSTALLATION FOR GRANULATING SLAG

In a process for granulating slag, from a blast furnace or a smelting reduction plant, in which a granule/water mixture formed during the granulation is fed to a granulation tank and then to a dewatering installation, in which the slag granules are dewatered. H2S-containing vapors and gases formed during the granulation are at least partially condensed by injection of water in a condensation ...

Blast Furnace Slag - an overview | ScienceDirect Topics

A slag granulation plant basically consists of granulation, dewatering, and storage sections. Different granulation processes could be applied in granulation section. The liquid slag is either fed into a slag pot or it is directly fed via a runner to a granulation plant in order to produce conventional water GBFS.

Blast Furnace Slag | National Slag Association

Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace.When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a non-metallic product called blast furnace slag.
